Hey guys, thought I would share a couple of very simple mods I did that others may benefit from.

My P750ZM came with a wimpy little 240W AC adapter, that's really not adequate for a heavily overclocked 4790K and GTX 980M. I had a spare AC-100 (dual adapter) converter box and a spare Alienware 330W AC adapter.

I purchased one of these dongles to convert the Dell 7.5mm connector to a different size AC plug. It does not matter what connector is on the male end, all we need is the Dell 7.5mm female connection, so any similar dongle will work. The wire gauge is smaller than I would like it to be, but the cable is short. So far I have noticed no power handling restrictions. The cable and end plugs on the dongle do not get hot, so it seems good in spite of the small wire gauge. If you can find a dongle made with larger gauge wire that would be a better option than the one I linked, but it does seem to work fine. So, what I did from here is I sacrificed the crappy little 240W adapter and stole the cable off of it. I used the original cable and strain relief boot from the 240W adapter to replace the silly short pigtail on the AC-100. I soldered it in place of the short pigtail and it looks factory.

When soldering together the custom dongle, be sure to wire it correctly. Solder white to white. The ID signal wire and ground wire should be soldered together and that will tell your Alienware AC adapter to output the full 330W capacity.

I used the short pigtail from the AC-100 converter and spliced it with the Dell adapter dongle, so now I can plug the 330W Alienware AC adapter into that dongle and connect it to a 4-prong Clevo laptop AC jack... easy-peasy. I can put my spare 330W Alienware adapter to good use on my Clevo laptops and now I have a nice long cord on my AC-100 converter box.

Hi, I tried to solder the original plug-in jack of my 180w PSU to a DELL ( Flextronics) 240w PSU. I connected the ID wire to the ground and white to white as you instructred, but the Adapter shuts down 1-2 min after GPU is under full load. I have a Clevo P157SM and upgraded 2 summers ago to a GTX 980M which needed more power. It is only doing this while using prema's vbios. I didn't change any settings. My laptop was working well with the 180w as well, but many users reported that it needs more power. Need a bit of help. Thanks!

What are you doing that shuts it down? If you're cranking up the GPU voltage you can still shut down a 240W with a single 980m.

CPU has been delidded and repaste has been done on both CPU/GPU dies with gallium based TIM-Coolaboratory liquid ultra if I recall correctly.

My issue is GPU hitting max temp limit of 90 degrees while playing DOOM and framerate drops from 110 avg to mid 60s-70s with horrible stuttering- this is thermal throttling for sure.

System was running beautifully after repaste at 86 degrees max/ 77 degrees average at 100 percent fan speed. A month later I decided to see how much further I could push the system and ended up undervolting the CPU/GPU and RAM even further. The RAM undervolting part didnt work as well as I'd hoped, and I ended up resetting the BIOS to undo everything and reapply the previous setting (-110 for CPU with turbo boost disabled.)

I noticed that immediately after BIOS reset, both my CPU and GPU temps were 5-10 degrees higher even with the undervolt/underclock applied. Also, I think the fans were a bit louder before I reset the BIOS which leads me to believe that for some reason the fans are now capped at 80% max fan speed. There doesnt seem to be a fan speed selector in the BIOS or anywhere else so I cant say for sure whether this is a fan related issue or something else.Before the reset I could override the BIOS setting and set the fans to 100% by pressing fn+1, could I have done something to that setting after resetting the BIOS ? I dont think I have damaged the CPU or GPU as temps are holding fairly steady at 90-91 degrees and laptop doesn't shut down while gaming.

If I have overlooked something or if anyone reading this has any solution help would be greatly appreciated.
All settings/drivers/windows version/app version are exactly the same before and after BIOS reset.

BAKED BIOS FOR TM, KM, DM, P6, P4 SERIES with most menus and options unlocked.

THESE BIOS MODS ARE ONLY FOR PEOPLE WHO KNOW WHAT THEY ARE DOING!

NEW:
I'VE BEEN BUSY WITH SOME STUFF PLUS MY SYSTEM HASN'T BEEN WORKING FOR SOME TIME BUT I SHOULD BE ABLE TO CONTINUE MY WORK SOON

I'M CURRENTLY WORKING ON V3.0 WHICH WILL INCLUDE UPDATED UEFI DRIVERS, MICROCODE BIOS SCREEN SHOT SUPPORT AMISCE SUPPORT(For some models) PLUS MORE.
I'M ALSO WORKING ON MODS FOR OTHER MODELS TOO.
ALL TM, KM AND DM SERIES ARE V2.0 AND NOW HAVE WINDOWS FLASHER INSTEAD, JUST EXTRACT AND RUN FLASH.BAT

WARNING! BIOS FLASHING IS RISKY SO MAKE SURE YOU KNOW WHAT YOU'RE DOING BEFORE PROCEEDING.
FLASHING THE WRONG BIOS OR INTERRUPTING THE FLASHING PROCESS WILL BRICK YOUR SYSTEM!
USE AT YOUR OWN RISK!

It has been a while since I did anything to my laptop (Clevo P670RG-G) and since I recently got a VR Headset I wish I could overclock my GPU a little. So far the NVidia software (on windows) doesn't allow me to overclock it (the linux sort of allows, which some custom Xorg options) so I decided to give a try modding the vbios.

I read all sorts of issues / guides about it, and it seens that the hardware topology (where the vbios is stored and how things are connected) changes from machine to machine.

What I know about my laptop is that it has two VBios, one for Hybrid Mode and one for Discrete Mode. I'm currently running the discrete mode.

I dumped my VBios using GPU-z and opened up in Maxwell II Bios Tweaker. Everything seens fine so far.

So I have few questions about it:

- There is a way to just unlock the VBios to show the overclocking options in NVidia software? (That way I dont need to reflash to change clocks)
- I can just flash this GPU-z dump to my VBios?
- If I brick my GPU, that GPU-z dumped image is the raw SPI image, so if I managed to physically access the VBios, I can just reflash over it?
- I saw some people saying that I might need as well to flash the main laptop bios as well, is that really needed?

There are several threads on requesting BIOS modifications here on T | I but I thought another one wouldn't hurt.

Your request should look like:
Brand
Model
Type of modification(For example: Unlocked, added support, Logo, microcode, ME firmware etc
I'll respond as soon as I have time as I'm also currently working on other projects(Requests by PM is also ok)
If anyone else have the knowledge and time feel free to respond to requests

Greetings, I have a p650rs and I have this little problem that I can not play in MRHYBRID mode, only if the charger is connected, and I do not see high quality videos or play if it is in discret mode, if the A / C is connected.

Any idea what it could be?

I have the latest version of Bios and ECF
I've been looking for custom-made Vbios but I can not find anything.
Thank you
